#9346: AtomicPrimOps tests failing on 32-bit x86 -------------------------------------+------------------------------------- Reporter: niklasl | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Keywords: | Differential Revisions: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: -------------------------------------+------------------------------------- concurrent/should_test/AtomicPrimops test fails on 32-bit archs as reported on the mailing list by Páli Gábor János [http://www.haskell.org/pipermail/ghc-devs/2014-July/005706.html]. More info: AtomicPrimOps.hs flakes out for: fetchAndTest fetchNandTest fetchOrTest fetchXorTest casTest but not for fetchAddSubTest and readWriteTest. If I step through it, the segfault comes at line 166, it doesn't reach the .fetchXXXIntArray function that was called from the thread (at least ghci doesn't hit a breakpoint set at it). GDB says the bad instruction is: 4475: f0 8b 4c 24 40 lock mov 0x40(%esp),%ecx -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9346 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
